illegal gun sales

Mayors Against Illegal Guns was started by Michael Bloomberg and former Boston Mayor Tom Menino in 2006. De Blasio pledged to aggressively work locally and on the national level to combat illegal gun sales and gun trafficking.

Nearly one-third of gun ads on ArmsList.com were posted by high-volume sellers who do not possess the mandatory federal firearms license. They use the “private sale loophole,” which does not require a background check, Bloomberg said Thursday.
